## What is Train Knot?

Every train in the yard is stuck behind another. Tap a train and it drives off along its track, if the way is clear. Pick the wrong one and it bumps into a blocker and costs a heart. Find the order that gets every train out.

Easy to learn in one tap. Hard to master by level 100.

HOW IT PLAYS
• Tap a train to send it down its track and out of the yard
• Trace each track: corners, crossings and blockers hide further down the line
• 3 hearts a level, so think before you tap
• Clear the yard fast for up to 3 stars

WHAT'S INSIDE
• 100 levels across two yards, the Siding and the Depot, growing from 3 trains to 9
• Daily Jam: one hard yard a day, the same for every player. Keep your streak going
• Game Center leaderboards for levels, the Daily Jam and your total stars
• 25 trains to collect in five packs, from the hand car to the maglev, each with its own look for your yard. One train from a pack opens its 20 levels
• Hints that show which trains can leave, and a crane that lifts one train out when you are truly stuck
• Your progress follows you to every iPhone through iCloud
• Light and dark themes

FAIR TO PLAY
• No pop-up ads. No interstitials. No ad ever interrupts a level
• Banners sit outside the yard, never over it
• Videos only when you choose to watch one, and the reward is shown before you tap
• 5 new levels free every day (unlimited on your first two days). Replays are always free

SUPPORTER
One purchase, yours for good: no banners, unlimited new levels, unlimited revives and double coins. Hints and the crane stay limited for everyone, so the puzzles stay puzzles.

Short on time? A level takes about a minute. Tap, think, untangle.
